YAMAHA YST-SW800

Commentary

Active subwoofer that uses QD-Bass technology.

The unit is equipped with 25 cm cone type woofer.

QD-Bass technology is adopted.
In this system, the woofer unit is installed downward and a pyramidal diffuser plate is installed on the bottom to efficiently radiate low-temperature energy in four horizontal directions. This realizes smooth frequency characteristics and free setting regardless of installation location.

The enclosure uses the Advanced Yamaha Active Serve Technology (A-YST) system.
Based on the concept of an air woofer that uses air itself as a diaphragm, the A-YST system enables low-frequency playback equivalent to that of a large speaker even in a small enclosure.

Equipped with an auto standby function.

Equipped with a B. A. S. S. mode switch.
Movie/Music can be switched, and low sound playback is possible depending on the source.
